Impact by Logix family PLC Member

  • ControlLogix users: You should be able to use the existing Version 5.5 driver without issue, however we strongly recommend you update to the latest version when released. If you get this error specifically, and know that your PLC is properly configured, please contact us if you need to get communications going before the update is available.

  • MicroLogix 1100: We know this issue affects MicroLogix 1100 users. If you are using this PLC and have recently upgraded from Version 5.4, please contact us if you need to get communications going before the update is available.
  • Other Logix PLCs and users of ControlLogix Gateway: this issue may affect the ability of TOP Server to connect to your PLCs. If you are having difficulty communicating to the PLC and are absolutely sure the configuration is correct, please install the updated version when available, or contact us for alternative solutions if you cannot wait.
